The characteristics of materials used in construction have a significant impact on the performance of
the resulting concrete. Coarse and fine aggregates are crucial components in cement concrete,
influencing its strength and workability. Research has shown that the type of aggregate used, whether
coarse or fine, plays a critical role in these properties. In this study, we examine the combined effect of
flaky aggregates and steel slag as partial replacements for coarse aggregates on concrete performance,
with marble powder replacing sand. Flaky aggregates and steel slag were incorporated at 10%, 15%,
20%, 25%, and 30% of the coarse aggregate content. Two concrete mixes were prepared with sand-to marble powder ratios of 1:1 and 1:0.5. The findings indicate that increasing the proportion of flaky
aggregates reduces both the strength and workability of the concrete. Conversely, adding steel slag
enhances concrete strength but decreases workability. Using both materials together boosts early
strength but results in lower overall strength gains and reduced workability.
